IBIS-Rover: Interferometric Mine Slope Radar




Quick set up: self-contained and fully integrated system, including automatic geocoding;

Mobile system: ideal where frequent relocation is required;

Multiple radar integration: with the FPM360 Full Pit Monitoring platform;

Wider coverage: enlarged field of view of up to 270°;

Ideal for open cut long-wall operations and small-size pits.



The IBIS-Rover is the most recent addition to the IBIS family of slope monitoring radar for mining applications.

It provides all the functions and proven benefits of the IBIS-FM systems: highly accurate real-time measurements of mine wall movements as well as reliable early warning for impending failures, with the added value of high mobility and fast deployment.

The IBIS-Rover is ideal for:

  • Rapid installation when urgent active monitoring is required;
  • Long-wall open cut operations (i.e. coal strip mining operations);
  • Multiple open-pits or pits with complex geometry;
  • Wherever frequent relocation is required and long range capabilities are not needed.
  • Modular composition tailored to user requirements;
  • High mobility at ranges of between 50 and 2,500 meters;
  • Real-time monitoring at ranges of between 50 and 2,500 meters;
  • Fast scan time of about 1 - 3 minutes;
  • Alarm generation with user-defined levels and multiple alarm/multiple area criteria;
  • Fully geo-referenced outputs projected visually in a radar view or in high quality DTM, exportable to 3D mine mining packages;
  • Robust automatic atmospheric correction;
  • Operates in all weather conditions;
  • Fully self-powered operation with approximately 15 days of autonomous power;
  • Operating temperature between -10°C and +55°C and an optional low-temperature kit which can extend the range to -35°C.

Guardian Software

IBIS-Rover is supplied along with Guardian, a software program specifically designed for critical and background monitoring. Guardian provides automatic real-time processing of radar data, visualization of displacement maps with multiple analysis options (extraction of time series for displacements, velocity, inverse of velocity) and the possibility to create multiple hazard-maps with user-defined alarm criteria for active monitoring.

IBIS Guardian makes use of state-of-the-art automatic atmospheric correction algorithms to provide accurate and reliable displacement maps fully geo-referenced with the digital terrain model.

The capability to handle long-term projects with large datasets makes Guardian also suitable for the long-term tracking of movements, potentially useful for regulators, for back analysis of slope failures and for more comprehensive geotechnical/geological analysis.
